As part of the European green deal, the European Commission is committed to aligning the air quality standards of the European Union with the WHO recommendations. These were revised in September 2021 by dividing by two the annual guide values for fine particles (5µg/m3) and by four that for nitrogen dioxide (NO2).
The proposed revision of the Ambient Air Quality Directives will set interim 2030 EU air quality standards, aligned more closely with World Health Organization guidelines (WHO guidelines for...
What Is PTFE Fabric?
PTFE stands for polytetrafluoroethylene, a kind of artificial polymer called a fluoropolymer.
A fluoropolymer is a polymer that includes carbon as well as fluorine particles. The primary element of polytetrafluoroethylene is tetrafluoroethylene (PTFE), a participant of the fluorocarbon member of the family. The essential high quality of PTFE is hydrophobic because of its decreased dielectric uniformity, which indicates that water can not experience this fabricated item. In enhancement, PTFE...
Neoprene-coated fiberglass fabric is a commonly used coating composite material in the industry. This material has excellent high and low-temperature resistance and is waterproof, oil-proof, ozone-resistant, and anti-aging, so it is widely used in various industries.
Then in the production process of neoprene, the adhesion of the butadiene rubber glue to the glass fiber cloth significantly influences the product`s quality. Guangzhou Daozhi Fiberglass provides some suggestions based on years of manufacturing...
Regulators in New Mexico recently capped off a multi-year effort to reduce methane emissions from the oil and gas sector with the release of the New Mexico Environment Department’s (NMED) final Ozone Precursor Rule. So, what’s in the rule and what does it mean for the future of methane emissions in New Mexico? Read on to find out.
First, a point of clarification. Although the rule is commonly referred to as a “methane” rule, it also targets important ozone precursor pollutants: volatile...
